Sophos UTM Smart Installer (aka SUSI) with third party ISOs

Question

Does anyone know a way to burn a third party ISO to the emulated USB CD-ROM drive on the stick? 
 I tried some tools but the most don&acute;t see the drive :( 
 Maybe someone has a smart idea?

I'm pretty sure it's not an official way and it's not supported at all but to do what you want but just change your desired ISO image name to any supported ISO filename . It works. 
 (I mean, you want to burn ubuntu.iso with SUSI, just rename the iso to something like "ssi-9.358-3.1.iso" (take a look here for more names https://www.sophos.com/es-es/support/utm-downloads.aspx ) Your ubuntu ISO will appear in SuSI like an ASG image, and you are ready to go.
